Answer:
If the density of the object is high its molecular arrangement is compact while if the density is lows its molecular arrangement isnt that compact
The 1st one is basically B because it will stay in motion with the same speed and in the same direction unless acted on by an unbalanced force and the 2cd one is A because most of is transformed into thermos energy. hope this helps!
Would be A 1012 N/C because The magnitude of the electric field at distance r from a point charge q is E=k

making (e) the best choice for this question.
Answer:
formula
speed = distance / time
distance = speed x time
distance = 346 x 5
distance = 1730 m
The distance of the lightening strike would be 1730 m or 1.7 km
Explanation:
I can't give you the actual number of turns, because it's the RATIO
that counts.
However many turns the primary has, the secondary should have
about TEN TIMES that number. Then the transformer will multiply
the primary voltage by 10 ... 120 volts of AC at the primary will
become 1,200 volts of AC at the secondary.
Note that it HAS TO be AC. If the transformer is supplied with DC,
then 120 volts at the primary becomes zero volts at the secondary
and a big cloud of stinky smoke in the room.
